Derivatives, investments
Full-Time / Part-Time MBA
Derivatives Markets I (FINC-465-0)

This course counts toward the following majors: Analytical Finance, Finance.

This course covers the use and pricing of forwards and futures, swaps and options. Specific topics include strategies for speculation and risk management, no-arbitrage pricing for forward contracts, the binomial and Black-Scholes option pricing models and applications of pricing models in other contexts.

Topics in Finance (FINC-520-0)
Current research in topics such as international finance, empirical finance, capital structure and financial markets are analyzed. The seminar usually requires in-class presentations by students, as well as individual research projects.

Time Series Analysis (FINC-520-1)
The specification, estimation, and diagnostic testing of dynamic models involving economic time series present a host of unique statistical problems requiring the use of specialized inference procedures. This course provides an overview of some of the most important of these procedures. The focus will be on results most relevant for practical applications rather than formal proofs of theorems, with the various econometric techniques illustrated through problems in both macroeconomics and asset pricing finance.
